A spokesman for Southern California Edison, the operator of the San Onofre nuclear power generating station (between LA and San Diego, the big white dome-shaped thing off I-5) was trying to calm fearful Southern California residents today when he explained that the 84-acre generating station was built to withstand a magnitude 7.0 earthquake. He also told local media that a 25-foot-high "tsunami wall" of reinforced concrete stood between the plant and the immediately adjacent Pacific ocean.
Well, that's nice. But this Southern California resident remains concerned: the earthquake that devastated Japan last Friday, throwing various nuclear power plants into crisis and sparking worldwide fears of a major nuke accident, was a 9.0 "great quake." And the tsunami that soon followed? That was 33 feet high.
When the plant was built 42 years ago (42 years! That's forever in design-years!), scientists predicted a 6.5 quake could strike the plant. The designers of the San Onofre plant built with a higher threshold in mind. But man, not high enough, for my money. There's a geological fault just 5 miles offshore, and good odds we'll be hit by a "great quake" of our own, sooner or later.
For context: those documents from TEPCO, operator of the stricken Fukushima plant in Japan, that were obtained by reporters at the Wall Street Journal? They show that engineers tested the Fukushima plant to withstand a quake up to magnitude 7.9.

The EVATAR is a working model of a reproductive system made from a mouse ovary and bits of a human uterus, cervix, vagina, fallopian tubes, and liver. Developed by Northwestern University researcher Teresa Woodruff and her colleagues, the EVATAR is intended to help better test the effects of medicines and toxins on women. And now […]
Texas State University’s Body Farm (AKA Forensic Anthropology Center at Texas State University or FACTS) is a 45-year-old facility where the corpses of medical body donors are left to decompose so that researchers can observe the rate at which human remains are consumed by the elements, scavengers and microbes, allowing them to accurately date the […]
A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Thread count isn’t like one of those deceiving metrics like camera megapixels or Facebook friends—more threads are always better if you can afford them. If price was no object, we would all be snoozing soundly bundled up in 1.8 kilo-thread sheets every single night. Guess what? Price doesn’t have to be an object with this […]
Maybe it’s entirely because of podcast ads, but drag-and-drop tools like Squarespace have gotten immensely popular in recent years. While it’s definitely a great tool for any non-coders who want to get a small website up and running quickly, managing content with a primarily visual interface can become a pain once you have more than […]
When you can’t wait for the world’s longest meeting to end, the mindless leg bouncing makes your boredom obvious and just annoys everybody else. Everyone knows the TPS reports need the damn cover sheet, but some sadistic colleague keeps forgetting, probably on purpose just to eat into your lunch hour. Enough is enough!While serving a […]
